[0003] In the prior art, a dust suppressor for construction projects is disclosed with publication number CN219744305U. A water pump is used to pump water in a water tank into a sprayer for spray dust reduction. At this time, a bidirectional motor can be used to drive the gear to rotate. Due to the meshing of the gear and the tooth plate, the tooth plate is driven to move upward, thereby enabling the sprayer to be raised, thereby achieving the effect of adjusting the height of the sprayer. At this time, the servo motor can be started to drive the bearing plate to rotate, thereby adjusting the spray angle of the sprayer, thereby achieving the effect of increasing the coverage area of ​​the spray dust reduction.

[0004] Although the dust reduction coverage area of ​​the device can be improved, in the actual construction process, the size of the construction area is mostly not fixed, and the dust reduction range of the emission reduction device cannot be flexibly adjusted according to the on-site conditions, which will cause a waste of dust reduction water and reduce the dust suppression effect, greatly reducing the emission reduction effect of the device.

DETAILED DESCRIPTION

[0020] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0021] like Figure 1-Figure 4 A building environmental protection emission reduction device shown includes a chassis 1, and a sprayer 2 rotatably connected to the top of the chassis 1, an adjustment box 3 is fixedly connected to the top of the chassis 1, a gear 4 is rotatably connected to the top of the chassis 1, and the top of the gear 4 passes through the chassis 1 and is fixedly connected to the sprayer 2, an electric telescopic rod 5 is fixedly connected to the inside of the chassis 1, a sliding block 6 is fixedly connected to the output end of the electric telescopic rod 5, a rack 7 meshing with the gear 4 is slidably connected to the top of the chassis 1, the sliding block 6 is fixedly connected to the middle of the side wall of the rack 7, a plurality of groups of travel switches 8 are arranged inside the chassis 1, and connecting rods 9 are fixedly connected between each group of travel switches 8, and a contact block 20 for contacting the travel switch 8 is fixedly connected to the side wall of the sliding block 6;

[0022] When reducing emissions and dust at a construction site, first connect the external power supply of the entire device, then push the emission reduction device to the construction site, and at the same time connect the sprayer 2 to the water source, aim the sprayer 2 at the construction site, and then carry out dust reduction and emission reduction treatment on the construction site. At the same time, control the electric telescopic rod 5 to start and drive the sliding block 6 to move, thereby driving the rack 7 to move, thereby driving the meshing gear 4 to rotate, and then driving the sprayer 2 to rotate. Subsequently, when the sliding block 6 drives the contact block 20 to move forward and touch the travel switch 8, the travel switch 8 will transmit a signal to the controller, and then the controller controls the electric telescopic rod 5 to move backward, thereby driving the sliding block 6 and the contact block 20 to slide backward. When the contact block 20 contacts the rear end travel switch 8, the above operation is repeated, and the left and right swing dust reduction function of the sprayer 2 is repeatedly realized.

[0023] A fixed rod 10 is fixedly connected to the inside of the adjusting box 3, a moving block 11 is slidably connected to the bottom of the adjusting box 3 and is arranged through the fixed rod 10, a lower spring 12 is fixedly connected between the adjusting box 3 and the moving block 11 and located outside the fixed rod 10, a plurality of indented grooves 13 are provided on the top of the moving block 11, a conical block 23 is fixedly connected to the top of the moving block 11 and located beside the plurality of grooves 13, a limit plate 14 is fixedly connected to the inside of the adjusting box 3, an L-shaped rod 16 is arranged at the bottom of the limit plate 14 and at a position corresponding to the groove 13, a push rod 15 is fixedly connected to the top of the L-shaped rod 16, an adjusting rod 17 is fixedly connected between the outer wall of the L-shaped rod 16 and the connecting rod 9, and the travel switch 8 is electrically connected to the electric telescopic rod 5 through a controller;

[0024] When the dust reduction range needs to be adjusted according to the scope of the construction site, first press the pressing block 18 of the corresponding range downward to drive the push rod 15 and the L-shaped rod 16 to slide downward, and then the L-shaped rod 16 squeezes the inclined surface of the conical block 23, so that the moving block 11 slides on the fixed rod 10, and at the same time compresses the lower spring 12, and at the same time the moving block 11 slides to the other side to release the position restriction of the L-shaped rod 16 originally stuck in the groove 13, and then the elastic force of the upper spring 19 pushes the pressing block 18 to drive the L-shaped rod 16 to slide upward to reset, thereby adjusting the rod 17 and the connecting rod 9. Pull the corresponding travel switch 8 to slide upward. When the L-shaped rod 16 moves to the groove 13, the squeezing of the conical block 23 will be released, and then the elastic force of the lower spring 12 will push the moving block 11 to reset, so that the bottom of the conical block 23 is stuck on the upper surface of the L-shaped rod 16, and the L-shaped rod 16 is locked. At the same time, the L-shaped rod 16 slides downward and drives the corresponding connecting rod 9 and the travel switch 8 to slide downward through the adjusting rod 17, so as to adjust the moving distance of the sliding block 6 and the contact block 20, and then adjust the rotation angle of the gear 4, so as to adjust the dust reduction range of the sprayer 2.

[0025] In order to facilitate the rapid adjustment of the dust reduction range of the sprayer 2, the top of the push rod 15 passes through the limit plate 14 and is fixedly connected with a pressing block 18. A through groove 22 is provided at the top of the adjustment box 3 and at a position corresponding to the pressing block 18. Through the setting of the pressing block 18 and the through groove 22, it is convenient for the staff to press the push rod 15, thereby quickly adjusting the dust reduction range of the sprayer 2, thereby improving the convenience of the device. At the same time, prompt numbers can be pasted on the surface of the pressing block 18, so that the staff can accurately understand the size of the adjustment range of each button. An upper spring 19 is fixedly connected between the bottom of the pressing block 18 and the limit plate 14. Through the setting of the upper spring 19, it is convenient to pull the L-shaped rod 16 to quickly reset.

[0026] In order to enable the equipment to achieve the effect of multi-stage adjustment of the dust reduction range, each group of travel switches 8 is equidistantly arranged, so that the moving distance of the rack 7 can be gradually increased, thereby realizing multi-stage adjustment of the rotation angle of the sprayer 2, and each group of connecting rods 9 is sequentially arranged on the outside of the previous group of connecting rods 9. Through the sequential arrangement of the connecting rods 9, when one group of travel switches 8 is pressed and driven downward by the connecting rods 9, it will not be hindered by other connecting rods 9.

[0027] In order to increase the service life of the equipment, a protective shell 21 for blocking water is hingedly connected to the top of the regulating box 3. The setting of the protective shell 21 can protect the parts in the regulating box 3 from rain and avoid being exposed to the air for a long time and being eroded by dust and water, which will affect the service life of the equipment.
